Effects of anthelmintic treatment on ewe feed intake, digestion, milk production and lamb growth

SUMMARYTwenty Small Tailed Han (STH) and 20 Ujumqin (UJU) ewes naturally infected with gastrointestinal nematodes were randomly assigned to one of four treatments arranged in a 2 × 2 factorial design, receiving anthelmintic treatment (AT) or non-anthelmintic treatment (NonAT) prior to lambing. After lambing, the effects of AT on feed intake, digestion and milk yield in ewes, and the growth rates of lambs fed their mother's milk were assessed for 28 days. Faecal samples were collected to determine faecal egg counts (FECs), milk was collected to measure milk yield and ewes and lambs were weighed to quantify daily body weight change. The results showed that AT significantly increased ewe dry matter intake (2411 g/d for AT and 2209 g/d for NonAT) and decreased FECs (50 eggs/g for AT and 2655 eggs/g for NonAT). All ewes lost weight after lambing, but body weight loss in the AT (43 g/d) was significantly less than in NonAT (84 g/d), and STH ewes (70 g/d) lost more weight than UJU ewes (58 g/d). Anthelmintic-treated ewes produced more milk for their lambs to consume. However, the extent of these positive effects of AT differed between STH and UJU ewes. The average daily body weight gain of lambs in AT was higher than those in NonAT. In conclusion, effective AT in ewes before lambing benefits subsequent lactation in ewes and growth rate in lambs.

Production Response

A series of three trials, two with lactating cows and one with growing heifers on pasture, utilized over 200 cows and heifers to establish whether there was a production response to the anthelmintic, "Tramisol" (levamisole phosphate). The lactating cows were subdivided into control and treated animals at parturition. Treated animals were injected with Tramisol on the day following parturition and 8 wk later. Heifers were treated when they were put out to pasture and every 4 wk thereafter. In the first trial with lactating cows there was no effect of treatment on milk yield or milk fat percent but body weight loss was less during the first 84 days for the treated versus control cows. In the second trial with lactating cows, milk yield was higher for total lactation and from 57 to 180 days for the treated cows. Body weight loss was also less during the first 50 days of lactation. There were no differences between the control or treated groups in either number of services required or days open. Heifers injected with Tramisol, when put on pasture, gained more body weight than control animals, particularly during periods of stress. Considering that the parasitic infestation in the herd was low the positive responses observed in these trials, although variable, warranted the conclusion that, in the majority of dairy herds in the area, routine anthelmintic treatment would be beneficial.

Abstract The aim of the research was to study the effects of synchronization index in the sugarcane bagasse based complete feed on feed intake, daily body weight gain and feed conversion ratio of sheep. Two permanent cannulated male local sheep was 2 years old to create formulation of three diets with different synchronization index, namely 0.37; 0.50 and 0.63 respectively. Fifteen local male sheep with body weight average of 18,32 kg (cv= 14,39%) and aged at 12 months were feed a complete feed based on bagasse with a level of synchrony index 0,37; 0,50; 0,63 were design isoprotein and isoenergy. The treatments were allotted in a randomized block design with 3 treatments and 5 groups for in-vivo test. The feed intake, daily body weight gain and feed conversion ratio of fifteen rams were determined on week 8 of experimental period. The results of the study indicated that the synchrony index did not effect on feed intake, but daily body weight and feed conversion ratio was affected (P<0.05) by the treatment of synchrony index in diet. The daily body weight gain of P2 group was highest compared with P1 and P3 groups. The feed conversion ratio of P2 group was lowest compared with P1 and P3 groups. The alteration of the study indicated that the synchronization index level of 0.50 showed the best weight gain and feed conversion.

Milk Fat Depression

Heat-stressed dairy animals increase their reliance on glucose. This elevated glucose demand is partially met by increasing the conversion of glucogenic amino acids (AA) in the liver. Propylene glycol (PG) is a glucogenic precursor and was not tested in dairy goats under thermoneutral (TN) and heat stress (HS) conditions simultaneously. We hypothesize that if HS-goats are fed with PG, they would get more glucose and consequently spare more glucogenic AA for milk protein synthesis rather than gluconeogenesis. Eight multiparous dairy goats (40.8 ± 1.1 kg body weight; 84 ± 1 days in milk) were used in a replicated 4 × 4 Latin square design of 4 periods; 21 d each (14 d adaptation, 5 d for measurements, and 2 d of transition). Goats were allocated to one of 4 treatments in a 2 × 2 factorial arrangement. Factors were control (CO) without PG or 5% of PG, and thermoneutral (TN; 15 to 20 °C) or heat stress (HS; 12 h/d at 37 °C and 12 h/d at 30 °C) conditions. Feed intake, rectal temperature, respiratory rate, milk yield, milk composition, and blood metabolites were measured. Compared to TN, HS goats had lower (p < 0.01) feed intake (–34%), fat-corrected milk (–15%), and milk fat (–15%). Heat-stressed goats also tended (p < 0.10) to produce milk with lower protein (–11%) and lactose (–4%) contents. Propylene glycol increased blood glucose (+7%; p < 0.05), blood insulin (+37%; p < 0.10), and body weight gain (+68%; p < 0.05), but decreased feed intake (–9%; p < 0.10) and milk fat content (–23%; p < 0.01). Furthermore, blood non-esterified fatty acids (–49%) and β-hydroxybutyrate (–32%) decreased (p < 0.05) by PG. In conclusion, supplementation of heat-stressed dairy goats with propylene glycol caused milk fat depression syndrome, but reduced body weight loss that is typically observed under HS conditions. Supplementation with lower doses of PG would avoid the reduced feed intake and milk fat depression, but this should be tested.

The objective of this experiment was to determine the effect of rejecting milk on drinking water on feed intake, daily body weight gain and feed conversion of broilers. The material of this study included 200 broilers aged 14 days given P0= drinking water treatment without giving an reject milk and P1= drinking water with the addition of rejected milk. Chickens were treated for 14 days and fed with PK= 22.0-23.0%, Fat= 5.0%, Calcium= 0.9%, Phospor= 0.6%, ME= 3050-3150 Kcal/Kg. In conclusion, rejected milk in drinking water has a significant effect on daily body weight gain, but does not significantly effect on feed intake and feed conversion. The daily body weight gain of P1 was higher than P0. Keywords: broilers, daily weight gain, feed intake, feed conversion ratio, rejected dairy milk

AbstractWeaning is a stressful period for the piglets and the sow. Stress during weaning is related to the change of diet which can affect the physiology of the gastrointestinal tract, as well as the microbial and immunological status of the animals. In the experiment a yeast-whey preparation was used to decrease the transient growth depression related to reduction of feed intake by the piglets. The piglets were assigned to three treatments. In the control group (I) the animals obtained standard feed mixture used routinely at the farm. In the case of piglets from II and III treatment, the yeast-whey preparation was added in the quantity of 4 and 7%, respectively.Application of 7% yeast-whey preparation to the diet significantly increased the body weight of piglets (p<0.05) and in consequence the average daily body weight gain (p<0.01) in comparison with the control group of animals. Additionally, piglets which were fed the yeast-whey preparation diet had a higher feed intake (p<0.05) and better feed conversion ratio (p<0.05) than those fed a diet without the addition of this preparation. No significant differences were stated for most biological parameters (p>0.05), except for the blood urea level, which was significantly lower (p<0.05) in the treatments where the yeast-whey preparation was used. These results indicated that yeast-whey preparation efficiently suppressed post-weaning diarrhea and improved the performance of the animals.

The aim of the study was to determine the effect of supplementing broiler chickens’ diets with halloysite on daily body weight gain (BWG), feed conversion ratio (FCR), daily water consumption (DWC), and some broiler house hygiene parameters. The trial was conducted on 18,000 broiler chickens divided into two groups throughout the 42-day (D) rearing period. The birds were fed complete diets without (group C) or with halloysite addition (1%, group E) from D8 of rearing. No difference in the mortality rate was observed between groups C and E. Birds from group E had a tendency (0.05 < p < 0.10) towards a higher body weight at D32 and D42, a higher BWG, and a lower FCR compared to group C during the entire rearing period. Average DWC differed only in the finisher period, with a tendency towards lower overall DWC in group E. The concentration of ammonia in the air from D21 to D35 was increased more than 5-fold in group C but only 1.5-fold in group E. In conclusion, the use of halloysite as a feed additive in the diet of broiler chickens resulted in a reduction in feed consumption per unit of BWG and higher utilisation of crude protein, which led to improved environmental conditions.

Mixed Breed

We tested whether the milk yield capacity of mixed-breed goats on a Chihuahuan desert rangeland in northern Mexico during the dry season affects milk composition, body weight gain, and weaning weight of their progeny. Milk yield and composition, and progeny postnatal growth performance, were recorded weekly. One week after kidding, mixed-breed goats (a mixture of Criollo × dairy breeds; n = 40) were allotted into medium (MP) or low (LP) milk yielding groups (20 goats per group). Mean 105-d total milk yield for MP and LP goats was 45.2 ± 12.5 and 20.7 ± 5.2 L, respectively. Milk lactose (4.3 vs. 4.2%) and solids-non-fat (SNF; 8.2 vs. 8.0) differed (p < 0.05) between MP and LP goats; milk protein content tended to differ (p = 0.08) between MP and LP goats with no difference for milk fat content (p > 0.05). Maternal body weight was positively associated with milk yield, milk lactose, and SNF content (p < 0.05 to p < 0.001). Goats giving birth to males produce more milk than goats giving birth to females, but milk fat percentage was higher in goats bearing females (p < 0.001). Milk yield and composition throughout lactation did not influence body weight gain (47.8 vs. 48.7 g/day for kids from MP and LP goats) and weaning weight (6.7 vs. 6.7 kg from MP and LP goats) of the offspring (p > 0.05). Birth weight and weaning weight of the progeny were positively related to maternal body weight (p ≤ 0.05). The postnatal growth of the kids was reduced, extending the time to reach market weight. Nevertheless, non-supplemented mixed-breed goats reared on semi-arid rangeland of northern Mexico have the potential for moderate milk production. Therefore, due to the limited nutrients ingested by grazing goats during the dry season, a nutritional supplement is necessary to keep up milk production and adequate growth of kids.

An experiment was carried out to determine the growth performance and haematological indices of Red Sokoto goats placed on oil palm leaf meal (OPLM)-wheat offal based diet. Six goats aged 12-18 months, weighing 15 – 20kg were randomly assigned to three treatments, comprising two animals each in a Completely Randomized Design. Each animal received 1kg of the diet daily for 56 days and weighed weekly. Results showed that final body weight was significant (P<0.05) with goats on T3 having the highest (21.50kg). The feed intake, body weight gain and Feed Conversion Ratio (FCR) were significantly different (P<0.05). T3 had the highest feed intake (305.35g/d), highest body weight gain (90.84g/d) and the best FCR (3.36). Significant differences (P <0.05) were observed in the Red Blood Cell (RBC), Packed Cell Volume (PCV) and Haemoglobin (Hb) counts, ranging between 3.12 - 4.20x106ml; 23.00 -30.50% and 7.70 - 10.15g/dl respectively with goats on T3 having the highest. The inclusion of OPLM enhanced body weight gain, FCR, RBC, PCV, and Hb counts of the goats. Therefore the oil palm leaf meal diets are recommended for better goat production.
