A study was conducted to determine the growth performance and carcass characteristics of indigenous Venda chickens fed a grower’s diet supplemented with varying levels of garlic meal. The study was based on four diets containing similar energy but different garlic meal supplementation levels of 0, 10, 15 and 25 g/kg DM. At 50 to 91 days, all the growth and carcass parameters measured were improved (P less than 0.05) by garlic meal supplementation. Feed intake, growth rate, feed conversion ratio, live weight, carcass weight, dressing percent, breast meat, thigh, drumstick, gizzard and fat pad weights of Venda chickens were optimized at different garlic meal supplementation levels of 14.7, 15.8, 8.0, 16.4, 14.2, 12.7, 11.2, 12.7, 8.2, 10.5 and 15.1, respectively. These findings have implications on ration formulation for indigenous Venda chickens. Thus, it was concluded that garlic meal supplementation improved feed intake, growth rate, live weight and carcass weight of Venda chickens.

A total of three hundred (300) day old unsexed “Fidan' broiler chicks averagely weighing 100.25 0.44g were used to study the response of broiler birds to diets containing different levels of yellow tigernut meal (TNM) as a replacement for maize. The birds were randomly allotted to five dietary treatments of three replicates each containing 60 and 20 birds respectively. After 28 days, the birds were again randomized based on weights to commence the finisher phase in a completely randomized design. The treatment diets consisted of 0%, 25%, 50% 75% and 100% of TNM as replacement for maize as diets 1 (control) 2, 3, 4 and 5 respectively. The result showed TNM to be low in protein (5.04%), moderate in fibre (13.01%) and high in ether extract (27.46%). Among the antinutritional factors, alkaloids, phytate and tannin were relatively high; 2.63mg/kg, 1.44mg/100g and 1.01mg/100g, respectively. Average weight gain (AWG) and final live weight (FLW) were high for birds fed 25 TNM and significantly (p<0.05) higher than the birds on control at the starter phase. However, at the finisher phase, the values were similar except for birds on 100% TNM that showed significant (p<0.05) depression in AWG and FWG. Feed intake was significantly affected by TNM inclusion levels and tended to improve (p<0.05) significantly as the level of TNM increases in the diets at the starter phase. And at the finisher phase, there was no significant (p>0.05) differences in feed intake across the treatment diets. The feed conversion ratio and protein efficiency showed similar trend both in starter and finisher phases of broiler production, except that at the starter phase, there was poor feed utilization as the level of TNM exceeded 25%, while at the finisher phase, depression only set in at 100% TNM. Feed cost (N/kg) increased as the level of TNM increased in the diets. Among the nutrient utilization only fibre and ether extract were significantly (p<0.05) affected and this occurred only at 100% TNM. The TNM inclusion had no significant effect on the dressing percentage. Of all the carcass parameters measured only gizzard, caeca and abdominal fat showed significant differences, which all tended to increase (p<0.05) significantly as the level of TNM increases in the diets. It was concluded that at starter phase TNM as replacement for maize should not exceed 25% and at finisher phase, it may not exceed 75% for optimal growth performance.

A six weeks trial was carried out to study the effect of feeding cottonseed meal (CSM) with 432, day - old Cobb 400 broiler chicks distributed to nine experimental diets with six replicates, each containing eight chicks. The experimental diets were formulated based on total amino acids (TAA) or based on digestible amino acids (DAA) with or without iron supplementation with two levels of CSM (2 and 4%) and control diet based on maize – soyabean. Birds fed with CSM at 4% DAA without iron supplementation had higher body weight gain than the control (1918 vs 1804g). Feed intake and feed efficiency were comparable in birds fed with different experimental diets. Inclusion of CSM up to 4% TAA or DAA with or without iron supplementation had comparable dressing percentage, gizzard, giblet (% of live body weight) and spleen (g). The liver weight (% of live weight) was lower in birds fed 4% CSM - TAA and 2 or 4% CSM - DAA with or without iron supplementation (1.45 – 1.53 vs 1.65%). Heart weight was higher (0.91 vs 0.80% of live weight) and abdominal fat (15.42 vs 24.0g) was lowered in 4% CSM - DAA with iron supplementation. The cost of feed/kg live weight gain in the diet of 4% CSM - DAA was lowest (52.77), followed by 4% CSM - TAA (55.43) and the difference with control was Rs 5.43 and Rs 2.77 respectively. The overall performance based on body weight gain, feed intake and feed efficiency was better in the diet formulated with 4% level of CSM - DAA.

Green tea leaves contain a wide range of active bio-compounds that are essential for sustainable quail intensification; however, its feed value is not known for the Jumbo quail. Therefore, this study evaluated the effect of different levels of green tea leaf powder (GTLP) on physiological and meat quality parameters of the Jumbo quail. One-week-old chicks (n = 350; 56.1 ± 2.12 g live-weight) were evenly distributed to 35 replicate pens and reared on five experimental diets formulated as follows: a standard grower diet with zinc-bacitracin (PosCon), a standard grower diet without zinc-bacitracin (NegCon), and NegCon diet treated with 10 (GT10), 25 (GT25) and 50 g/kg (GT50) of GTLP. Weight gain linearly decreased in week 2 but increased in week 4, whereas feed conversion efficiency linearly declined in weeks 2 and 3 as GTLP levels increased. Overall feed intake, carcass yield, and caecum and colon weights showed a linear increase with GTLP levels. Hematological parameters fell within the normal ranges reported for healthy quail. The GT10 group showed larger liver weights than the PosCon and NegCon groups. It was concluded that dietary inclusion of GTLP enhances overall feed intake and carcass performance but not feed efficiency, hematological and meat quality parameters of Jumbo quail.

Growth Trial

Abstract Mangalica pigs are a popular niche breed given their reputation for superior quality pork. However, growth and carcass parameters for this breed are poorly documented. Our objective was to better characterize optimal harvest weights for the Mangalica breed. To accomplish this, a growth trial was conducted whereby pigs (n=56) were randomly distributed across stratified harvest weights (50, 57, 68, 82, 93, 102, 127 kg) in a completely randomized design. Pigs were fed standard finisher rations with individual daily feed intakes and weekly body weights recorded for all animals. At 24h postmortem, carcasses were split and ribbed with marbling and loin eye area (LEA) measured at the 10th rib. Primal cuts were fabricated and individually weighed. Fat back was separated from the loin and weighed. As expected, live weight significantly increased across weight class (P &lt; 0.0001). ADG was similar across classes up to 82 kg live weight before steadily declining with increasing weight class (P &lt; 0.0025). Likewise, feed efficiency did not differ between classes until weights heavier than 82 kg (P &lt; 0.03). LEA significantly increased by class up to 82 kg and then plateaued as harvest weight increased further (P &lt; 0.003). Marbling score significantly increased with increasing weight class up to 102 kg where they then plateaued (p &lt; 0.04). Fat back dramatically increased across all weight classes (p &lt; 0.0001) despite negligible increases in LEA or marbling after 102 kg. Primal cut weights for the ham (P &lt; 0.0001), loin (P &lt; 0.0001), Boston butt (P &lt; 0.0001), shoulder (P &lt; 0.0001), and belly (P &lt; 0.0001) all significantly increased with increasing live weight. These data suggest an optimal harvest weight occurs between 82 to 102 kg while offering little objective justification for the current practice of harvesting Mangalica pigs at much heavier live weights.

Dietary Treatments

An experiment was conducted to determine the dietary effect of different levels of ground black pepper (Piper nigrum) on growth performance and apparent nutrient digestibility of broiler chickens. There were five dietary treatments each containing 0, 0.25, 0.50, 0.75 and 1.00 % black pepper (BP) fed at both starter and finisher phases. One hundred and fifty (150) day old chicks of Arbor-acre strain were divided into five dietary groups having three replication with 10 in each. The five dietary treatments were randomly assigned into five groups. The birds were fed and watered ad libitum. At the starter phase 0.25 and 0.5 % BP improved live weight significantly (p<0.05). Feed intake was significantly (p<0.05) reduced at 1.00% BP. There were no significant differences (P>0.05) in daily gain, feed: gain ratio and protein efficiency ratio. At the finisher phase, final live weight was improved by 0.25% (p<0.05). Final live weight, feed intake, weight gain, feed: gain ratio and protein efficiency ratio were negatively affected by 0.75 and 1.0%BP. Fecal moisture was significantly (P<0.05) reduced by 0.25% while dry matter, protein and ether extract digestibility were improved by all the levels of BP. None of the BP levels improved crude fibre digestibility (p>0.05) over the control. NFE and energy utilization were improved by 0.25 and 0.5%, but significantly (p<0.05) reduced by 1.00% BP.Bang. J.

The objective of this work was to evaluate the effects of two types of incubation and two types of feeding on the performance of chickens and intestinal development of chicks during the pre-starter phase (1 to 7 days of age). One-year-old male Ross® chicks were used. The experimental design was a randomized complete block design, in a 2x2 factorial design, with two types of feed processing (bran and micropelleted) and two types of incubation machines (single and multiple stage), totaling four treatments, with four treatment repetitions each. Twelve birds per experimental unit were used, totaling 192 animals. Performance evaluations were conducted, such as mean weight, weight gain, feed intake, feed conversion, bowel weight and size, and percentage of intestine in relation to live weight. Histomorphometric tests on the height of the villi and depth of the duodenal crypts were also performed. The two incubation machines did not influence any of the analyzed variables. Even though both had the same composition, the micropelleted feed resulted in positive gains for the performance variables: average weight, weight gain, feed intake, and feed conversion when compared to the meal, but was unable to significantly influence the morphometric measurements of the duodenum of chicks in the pre-starter phase.
